Updated Human Brain Map Reveals Nearly 100 New Regions!

In the early 1900s, neurologist Korbinian Brodmann drew some of the first diagrams of the human cortex by hand, based on differences in cellular architecture that he could see under a microscope.
For more than a century, scientists have continued using those maps, as well as those of neuroanatomists that followed in Brodmann’s footsteps. Now, neuroscientists have created a long-overdue update for those early diagrams, using anatomical and functional brain data from the Human Connectome Project—a large-scale, digitized effort to map the brain’s functions and structures from hundreds of human samples.
To create a more detailed map, the team looked at four measures of structure and function, including the thickness and number of folds in the cortex and what activity different regions displayed in a functional magnetic resonance imaging scanner during a given task. They gathered their data from 210 healthy adults, and then trained a machine-learning algorithm to detect distinct regional “fingerprints.” The program defined 180 distinct areas, including nearly 100 that have never been described before, the scientists report today in Nature.
